I googled 'images of the cross of knights templar' and the cross you want is in the second row on the right, then copied and enlarged, and then laminated the whole page and then cut out the cross. Dead easy. In Santiago you can also buy them in stainless steel, but hard to find, so suggest you ask at the Galician Tourist Office for places to buy it. My recipe is:
Set oven at 180 degrees centigrade
Thoroughly grease with butter 22cm dia pie pan with removable base
280gm of sugar
320gm of ground almonds (or almond meal)
2 heaped teaspoons of cinnamon
1 melted ice block of lemon juice *
5 eggs, mixed but not whipped
Mix dry ingredients thoroughly, add eggs and lemon juice and mix, pour into 22cm dia fluted pie pan, and bake for 40 - 45 minutes at 170 degrees centigrade. Remove from pan when cool.
* When lemons are in season, I but lots, juice and freeze in ice block trays and when frozen put in plastic freezer bags
